I think some changes are needed, no guns. But maybe a gun that shoots out LOVE and gOOdness lol OMG like those old school anime! haha... the 2nd image is those angels shooting love at the small demon. who became an good guy... I don't know would it work or back fires, but the message behind it is that 'bad beings can be turn to good and away from evil with love of GOD' not 'the love of man'.
